The 'Intrusive Target': A Compelling Case for a
Large Low-Grade Deposit under Thor!
Large Low-Grade Deposit under Thor!

The holes will test the magnetic body at two levels. The intrusive body that was modeled from the ground magnetics appears to have a juncture between two portions – an upper part that strikes NNW and a lower part that strikes almost east-west.
This juncture causes a significant magnetic feature at this location, and it is almost certainly related to intrusive rocks. The drill holes will also test the magnetic body where it appears that the Great Northern Zone projects down into the magnetic body, and there is a large conductive body lying on the top of the magnetic body. |
Two drill holes planned for 2021 are designed to test for the presence of an intrusive body that is found under the Thor deposit. This is an important feature since the presence of this body would suggest it is the ‘heat engine’ for the entire Thor deposit, and secondly – and most importantly, that the intrusive body itself could be mineralized.
The presence of the intrusive body is an interpretation is based on ground magnetic surveying and petrology investigations by the Colorado School of Mines that was completed on some “porphyritic” rocks found in Broadview Creek. The two drill holes will test the magnetic geophysical anomaly in an area below Broadview Creek where petrology has identified ‘hornfels’ – a rock closely associated with contact metamorphism and intrusive bodies. This hornfels also appeared to be mineralized with sulfide minerals including pyrite, tetrahedrite?/galena and it is known that sphalerite occurs in ‘dyke rocks’ further up Broadview Creek in previous drill holes.
